Abstract

A herbicidal composition containing ametryn, sulfentrazone and sulfasulfuron-methyl and its application in the present invention relate to a kind of herbicidal composition, which comprises ametryn, sulfentrazone and sulfasulfuron-methyl as active substance. The invention also relates to methods of using said herbicidal compositions for the treatment of undesired vegetation. A herbicidal composition containing ametryn, sulfentrazone, and sulfasulfuron-methyl contains active ingredients ametryn, sulfentrazone and sulfasulfuron-methyl. The herbicidal composition; wherein the weight ratio of ametryn to sulfentrazone is 30:1-1:30, and the weight ratio of ametryn or sulfentrazone to pyrisulfuron-methyl is 90:1 - 1:10; ametrazine, sulfentrazone, and sulfasulfuron-methyl together account for 5%-95% by weight of the herbicidal composition. The invention is mainly used for the prevention and control of weeds in sugarcane fields, corn fields, citrus gardens and other places, especially the control of Cyperus cyperi.

Description

technical field [0001] A herbicidal composition containing ametryn, sulfentrazone and sulfasulfuron-methyl and its application in the present invention relate to a kind of herbicidal composition, which comprises ametryn, sulfentrazone and sulfasulfuron-methyl as active substance. The invention also relates to a method for treating undesired vegetation using said herbicidal composition Background technique [0002] Protecting crops against weeds and other plants that inhibit crop growth is a recurring challenge in agricultural management. To help address these problems, researchers in the field of synthetic chemistry have produced a wide variety of chemicals and chemical formulations that are effective in controlling this unwanted growth. Many types of chemical herbicides are disclosed in the literature, and many types are commercially available. [0003] In some cases, herbicidally active ingredients appear to be more effective when applied in combination than when applie...
